In May 2023, Bitcoin exchange-traded funds (ETFs) saw significant outflows, totaling over $2.43 billion, marking the worst month of the year for these funds. This decline follows a period of growth, where Bitcoin ETFs had gained $3.2 billion in March and April. The leading fund, BlackRock's iShares Bitcoin Trust, experienced a notable outflow of $68 million in one day, contributing to a cumulative loss of $1.42 billion in just one week. This trend is largely attributed to a shift in investor focus towards the stock market, which has thrived due to the artificial intelligence boom, with the S&P 500 and Nasdaq 100 indices rising by 10% and 20% respectively. Major stock ETFs have also seen substantial inflows, with the Vanguard S&P 500 ETF adding $66 billion in assets. As Bitcoin struggles, remaining 41% below its all-time high, analysts suggest that the cryptocurrency may continue to face downward pressure in the near future.
